A 61-year-old construction worker from Plymouth was injured Tuesday afternoon when the dump truck he was driving tipped over, police said.

Acting Cohasset police Chief William Quigley said the driver was trapped inside the cab of the truck after it turned onto its side at a construction site off Beechwood Street at 12:20 p.m.

Police said it appeared the truck tipped over after the load shifted.

Firefighters freed the man, who was taken by Cohasset paramedics to South Shore Hospital with non-life-threatening injuries, Quigley said.

Quigley said the truck, owned by P.A. Landers Inc. of Hanover, was being used at the construction site of the housing development Cohasset Estates. Toll Brothers, a national housing developer, is building 41 homes there.

Quigley said a heavy-duty tow truck was needed because of the size of the dump truck.

The dump truck took down power lines when it fell, Quigley said, so National Grid was called to the scene.

Quigley said the federal Occupational Safety and Health Administration was notified, but it declined to investigate.
